Malicious URL (Uniform Resource Locator) detection method and malicious URL detection device

The embodiment of the invention discloses a malicious URL (Uniform Resource Locator) detection method and a malicious URL detection device which are used in the technical field of information processing. The malicious URL detection device divides the to-be-detected URL into multiple components, assigns corresponding detection scores for each component, and determines the total score of the to-be-detected URL according to the detection score of each component, if the total score is in a preset first score range of the malicious URL, the malicious URL detection device determines that the to-be-detected URL is the malicious URL. In this way, the malicious URL detection device can directly detect whether the to-be-detected URL is the malicious URL by the operations to the to-be-detected URL, rather than detecting whether the URL is the malicious URL by operating the content corresponding to the to-be-detected URL, thus, time for obtaining the content corresponding to the to-be-detected URL is saved, the detection efficiency can be improved, and the failure caused by failure in acquisition of the content of the to-be-detected URL is avoided.
